Beautiful glass water drop weather forecaster

These are beautiful art pieces that are shaped like a water drop. Listing is for one 5” x 2 1/2” drop with wood base. These have floating crystals inside that move kind of like a snow globe but prettier. The crystals change depending on weather conditions, my guess is pressure related. But buy it for the art, don’t rely on it to predict weather ;-). Seems like magic, no idea how they blow this glass and seal the liquid and crystals inside. Perfect gift 💧
